Venture Capital Markets: A Cross Country Analysis
No full textAbstractVenture capital (VC) may be defined as a support to entrepreneurial talents and appetite by turning ideas and basic science into products and services which are expected to envy the world. Venture capital funds are able to build companies from the simplest form to mature organizations. Venture capital investors generally actively engage with management of the company by typically taking place on the board. Through the due diligence process the venture capital firms concentrate on the founders, the management team, the concept, the marketplace, the revenue model, the value-added potential of the firm, the amount of capital needed to heal the business and whether all these fit to the fund's objectives. Over the next three to eight years, the venture firm works with the founding entrepreneur/s to grow the company. Once a company funded by venture capital matures and becomes successful, venture funds generally exit by taking it public through an initial public offering (IPO) or by selling it to big companies. This allows the venture funds to be free from the previous investment and invest in the next generation of companies. United States, Europe, Israel, Canada, China and India have the most developed markets for venture capital environment. The size of the venture capital market is nowadays about 33.1 billion in 2013. Venture capital firms may invest in promising firms in stages of seed, first round, second round or later. The median investment amounts in the United States in 2013 are 2.5 million for first round, 10 for later stage. The most attractive sector for venture capital is information technology for the United States, Israel and Canada, invested over 4.8 billion in 2013
Whether Development Indices Affect Economic Growth: A Cross-Country Analysis
No full textAbstractThis study aims to examine the relationship between economic growth and highly featured development indices using a cross sectional data of 12 countries from both developed and developing world between the years 2000 and 2013. The indices of corruption, democracy, freedom of press, human development, global competitiveness, economic freedom, and the featured development indicators of World Bank such as average schooling years, life expectancy, female labour force participation rate, health expenditures rate in GDP, export rate of high technology, and employment rate are used to investigate the relationship in between economic growth and development indices. In order to exploit this relationship, all individual indices are reformed to produce form a single index, what we call harmonic index. The findings show that the higher scores of harmonic Index are associated with higher GDP per capita all levels except Saudi Arabia
G20: On Behalf of the Rest?
No full textAbstractMajor developments in the last three decades have set the scene for the rise of novel problems on global scale. The unprecedented level of interdependence and interconnectedness between countries, firms and institutions has paved the way for the emergence of, both, novel practices that increase the quality of life and intriguingly complicated issues of global governance. The relationship between global actors are so intertwined that striving for predictability is barely feasible. In spite of the enhanced capabilities gained through involvement in the economic and financial value creation process, there are perils ahead for better global governance. Major issues pose global actors in terms of credibility, building and ensuring sustainability, erosion of capacity to fulfill promises and increasing fragility of financial markets as well as issues regarding depleting energy resources, environment and security. G-20 emerged as a remedial governance structure in the wake of the 2008 financial turmoil making sure that the prominent dynamic emerging countries are seated around the table. The expansion of G-8 into G-20 including the new global powerhouses has many positive implications. However, ongoing debates regarding this structure oscillate between hope and contestation. This conceptual paper intends to draw a general framework regarding the representative capability of G-20 members and discuss the hybrid quality of this so called steering committee given the era of turbulence that the world is heading towards
Simulation acceptance scale (SAS): A validity and reliability study
No full textA review of literature reveals serious problems in the validity and reliability of the measurement tools used in simulation technology acceptance studies conducted in the context of various technology acceptance models. To address this gap in literature, this study proposes a measurement tool that will allow a valid and reliable measurement of students' acceptance levels. The study was conducted in the 2017-2018 academic year and involved a group of 409 health sciences students. Exploratory factor analysis (EFA) was conducted to examine the construct validity of the conclusions based on gathered measurements. At the end of the EFA, a construct with a single factor and 24 items which explained 54.87 percent of the total variance was obtained. Based on the findings of the research, it was concluded that simulation acceptance scale produced from the EFA could be used for valid and reliable measurements regarding the general acceptance of simulation technologies by the health sciences students
Developing a virtual patient: design, usability, and learning effect in communication skills training
No full textAbstract Background Literature shows that Virtual Patients (VPs) find extensive usage in the field of health sciences, especially in the post-pandemic period. VPs are successfully utilized in developing various effective skills like medical interview. However, this technology is quite new in Turkey and has not yet been used in communication skills training in a structured form. This research aimed to develop a virtual patient to improve the communication skills of medical students. Methods Developmental research method was used in the study. The implementation phase involved the one group posttest quasi-experimental design. The study group comprised of experts in various fields and 213 medical students. Needs Analysis Form, Scenario Building Form, System Validation Form, Communication Skills Assessment Form, and Interview Form were used as data collection tools. The research primarily concentrated on ensuring minimal errors within the system and enhancing students’ communication skill scores. Results The study found that VP was effective in teaching communication skills. Communication skills improved from a mean score of 36.74 in the first interview with 15 students to 74.2 in the final application with 198 students. It was determined that the students who practiced repeatedly (n = 26) made 17% more effective interviews than their first practices (score: 89.2). The script matching of the VP was 83%. Other data obtained from the students generally showed that the VP application was developed in accordance with the purpose, that it was user-friendly, and that the scenarios were adequate. Conclusion VPs like this have the potential to develop skills such as history taking, clinical reasoning, etc., which are very important in the field of health sciences

No full textIn this work, we investigate the effect of disorder on the topological properties of multichannel superconductor nanowires. While the standard expectation is that the spectral gap is closed and opened at transitions that change the topological index of the wire, we show that the closing and opening of a transport gap can also cause topological transitions, even in the presence of nonzero density of states across the transition. Such transport gaps induced by disorder can change the topological index, driving a topologically trivial wire into a nontrivial state or vice versa. We focus on the Rashba spin-orbit coupled semiconductor nanowires in proximity to a conventional superconductor, which is an experimentally relevant system, and we obtain analytical formulas for topological transitions in these wires, valid for generic realizations of disorder. Full tight-binding simulations show excellent agreement with our analytical results without any fitting parameters.</p
